CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 275,428, dated April10, 1883.

Application filed October 24, 1882. (No model.)

To all whom it may concern Be itknown that I, JACOB G. SLA'IER, acitizen of the United States, residing at Albany, in the county ofAlbany and State of New York, have invented a new and useful Improvementin Car-Couplings, of which the following is a specification, referencebeing had to the accompanying drawings.

Figure l is a perspective view. Fig. 2 is a longitudinal verticalsectional view oi' the draw-head, showing the coupling-hook raised. Fig.3 is a longitudinal vertical sectional view of the draw-head, showingthe coupling-hook dropped and the link in position. Fig. 4 is a frontview. Fig. 5 is a detail view'of the coupling-hook detached, and Figs.6, 7, and S are detail views of parts of the coupling.

The same letters refer to the same parts in all the gnres.

This invention relates to automatic or selfacting car-couplings; and itconsists in certain improvements in the construction of the same',

which will he hereinafter fully described, and particularly pointed ontin the claims.

In the drawings hereto annexed, A represents the draw-head, having themouth or recess B, and provided with a "ertical slot, C, at the sides ofwhich lugs D D are cast, on the upper side of the draw-head, to receivea bolt, E, upon which an oval plate or eccentric, F, is mounted, asshown.-

G is the coupling-hook, which issubstantially-of the shape shown in thedrawings, and provided at its rear part or heel, G', with a slot, H, bywhich it is mounted upon a transverse bolt, I, in the draw-head A. Thecoupling-hook G is provided with an upwardprojecting shank or handle, J,by which it may be conveniently manipulated, or to which an operatingcord, rod, or chain may be attached.

K is a plate having in its under side, at its rear end, a recess, L, inwhich the front end of the oval plate or eccentric F is hinged by atransverse bolt, M. The front end of plate K has a slot, N, in which theshank J of the coupling-hook is hinged by a transverse bolt or pin, O.

The draw-head A is provided at the sides of the mouth or recess Bwithvertical openings P P, to receive the legs Q Q of avertically-sliding bail, It. The lower ends of the legs Q are bentinwardly, so as to form arms S, which extend into the mouth or recess B,the bottom of which is providedwith reccesses T to accommodate said armsS. The upper end of bail R has a loop, U,to which an 0perating-chain maybe attached.

The operation ot' my invention will be readily-understood from theforegoing description, taken in connection with the drawings heretoannexed.

When the coupling-hook is lifted it at the same time lifts lthe plate Kand eccentric F, which latter throws the said plate and hook in arearward direction to the position shown in Fig. 2, the slot Hpermitting the coup ling-hook to assume this position, in which it isretained by its own weight. When a link enters the draw-head it strikesthe heel of the coupling-hook, whichis thereby thrown forward to thelocked position shown in Fig. 3. By means of the hail It the link may beraised and guided into the draw-head of an adjoining car.

I claim as my invention- 1. In a car-coupling, the couplinghook G,having slot H, whereby it is pivoted upon the pin I, shank J, and heelG', the latter adapted to be struck by the link entering the drawhead,as set forth.

2. The combination, with the pivoted coupling-hook G, having slot H,whereby it may have a sliding movement when raised, shank J, and heelG', of the hinged or pivoted eccentric F and the connecting-plate K, asset forth.

3. In a car-coupling, the combination, with the pivoted coupling-hook G,having slot H, heel G', and shank J, of the eccentric F and theconnecting-plate K, having recess L to receive and cover said eccentric,and having its front end bifurcated and pivoted to the shank of thecoupling-hook, as set forth.

4. The herein-described improved car-coupling, consisting of thedraw-head A, having recess B andsiot C, the pivoted coupling- Intestimony that I claim the foregoing as hook G, having slot H, shank J,and heel G, my own I have hereto axed my signature in the eccentric F,connecting-plate K, and the presence of two witnesses.

vertically-sliding bail R, having arms S, eX- JACOB G. SLATER. tendinginto the month of the draw-head and Witnesses: accommodated in recessesT in the same, as E. W. GREENMAN,

set forth. MICHAEL MILLER.
